Hi Arend,
On our nightly test setups I found that STA->AP TCP iperf showed a
regression in brcmsmac after I upgraded them from 3.18-rc5
wireless-testing (f638577)to 3.19-rc1 wireless-testing (f9e7c6c). The
attached pictures are historic results showing clear drop on the last run.
Has there been any report on there since 3.19-rc1 and would you have a
pointer on where to start looking. The changes in brcmsmac look trivial
so looking at mac80211 now. There are some changes in minstrel and
brcmsmac is using minstrel_ht rate control.
I haven't heard of anything like that yet. No idea where to look either
- but the drop is significant enough that perhaps you can bisect?
Bisect it is. Was hoping for some obvious change to avoid that.
Regards,
Arend
